Missing account ID for ECDSA allowlist request

It seems ACMEv1 accounts were migrated to ACMEv2:

Existing Accounts

Existing ACME accounts from the production V1 API will work with the production V2 API. Authorizations held by a V1 account will not be usable in the V2 environment - you must revalidate your domains for use with ACME v2. Similar to ACMEv1, accounts from the V1 or V2 staging environment will not work in the production environment.

Maybe it's just as simple as just using your v1 account URI https://acme-v01.api.letsencrypt.org/acme/reg/4768?

Let's ask @lestaff if the migrated ACMEv1 accounts to the ACMEv2 endpoint are also usable in the ECDSA whitelist form. If so, maybe the form or Finding Account IDs - Let's Encrypt should reflect this possibility.
